For example sometimes you can get an error like this : $ service mysqld status ERROR! The server quit without updating PID file (/var/lib/mysql/pid). Check the log file at /var/lib/mysql/err $ tail /var/lib/mysql/err 120602 mysqld_safe mysqld from pid file /var/lib/mysql/pid ended This line tells us that we have a compatibility problem with some of our tables and mysql fails to start in safe mode.

My SQL is not running, but lock file (/var/lock/subsys/mysql) exists Well, it’s kind of obvious, just remove the lock file and restart the server. Now let’s change the way mysql starts to work around this situtation.

I would also like to Thank Jeff @ No Baloney for his warm voice and a few quick jokes while speaking with him on the phone.

This step-by-step guide is mainly for Free BSD, however the idea is the same for Linux.

I'm not sure why this line above didn't cause any issues with 5.1.55 and threw 5.1.56 into a frizzy...

however I wanted to mention this in case anyone else run into this issue.

It can be the problem of using an unsupported variable, or something similar.

The easiest way is to remove your configuration file, and try to start the My SQL server again: Backup your My SQL configuration first.

$ rm /var/lock/subsys/mysql $ service mysqld restart If none of these help, and you’re getting an error like this: $ service mysqld restart ERROR! $ /etc/init/Time to restart $ /etc/init.d/mysqld restart You should a get successfull restart. $ mysql_upgrade If it says you have the latest version, still force it.
